IHS is the inverse hyperbolic sine transformation of Number. Proportion Other-Coalition Neighbor is the proportion of left-right seating neighbors from a different coalition. MP-clustered standard errors are in parentheses and p-values are in square brackets. Randomization inference p-values (1000 draws) are in curly brackets. Special sessions and a short session (2017) are excluded. For lead and lag specifications, sessions are also dropped where lead/lag would be a special/short session or a session in a different parliamentary term. Strata FE is a dummy variable for whether MP was pre-assigned a seat. *** p<0.01, ** p<0.05, * p<0.1.} \\ \end{tabular} }
